Abstract

Abstract

The solar tower in CSP (concentrating solar power) station is usually characterized by large height-width ratio, low frequency and small damping which makes its response is rather sensitivity to wind loads. In order to study the wind-induced responses laws of the tower, a full-scale aeroelastic model for a 243-meter-high solar tower was designed and manufactured in the paper. Measurements of the model’s dynamic response indicated a good simulation of the parameters for the prototype tower and the first-order damping ratio was as low as 0.3%. Then wind tunnel test for the aeroelastic model was conducted, the influence of the damping ratio of the model on the wind-induced responses of the tower was studied, as well as the response laws of the structure in cross-wind and along-wind directions at vortex-induced vibration resonance and design wind speed. The results indicated that vortex-induced resonance occurred significantly at a velocity of about 22.1 m/s for the prototype tower. When the damping ratio was 0.7%, there was an obvious vortex-induced response, however, when the damping ratio of the structure increased to 1.0% or more, the vortex-indused response became less obvious. In addition, the maximum peak acceleration of the tower occurred in the cross-wind direction at the vortex-induced vibration wind speed while the maximum base shear response occurred in the along-wind direction at the design wind speed.
